A clip for holding first and second parts together snaps into an opening in a first part and includes a central housing for receiving and retaining a male portion on a second part using catches. The clip has a spring structure allowing sideways displacement of the catches so that it occupies either a locked position in which it projects into the central housing to prevent axial movement of the male portion, or a position of release of the male portion in which it is withdrawn from the central housing. The clip also includes a mechanism for causing the catches to move to their locked positions automatically by snapping the clip onto the first part.

1. A clip for holding a first and a second piece together, the first piece having an opening in which the clip is received and the second piece having a tang for insertion in the opening, said clip comprising: a summit base;a pair of external lateral legs returned elastically in a lateral direction towards an outside of said clip, said external legs engageable with the first piece upon axial insertion of said external legs in the opening;a pair of internal lateral legs, each disposed adjacent to an associated said external leg and defining, in combination with said summit base, a central space for axial insertion of the tang between said internal legs, each said internal leg having a catch element projecting into said central space for retaining the tang in said central space;each internal leg further including elastic elements for lateral displacement of the corresponding said catch elements between a locked position in which said catch elements project inside said central space for axial blocking of the tang and a tang release position in which said catch elements are disposed away from said central space;actuating means for displacing said catch elements towards said locked position, said actuating means actuable by snapping said clip in the first piece; andeach internal leg further comprising a first portion connected to said summit base and extended by a second portion bent backwards towards the outside of said clip in direction of said summit base, each backward bent portion comprising an elastically deformable folding zone and a blade carrying the corresponding said catch element, said folding zone positioning the blade when partially inserted within the opening laterally between said first portion of said adjacent external leg, while a portion of said blade is positioned laterally at a level of a clipping hook carried by said external leg. 2. The clip of claim 1, wherein each blade comprises a first section connected to said folding zone and pointing in an axial direction of said clip, and a second section laterally inclined towards an inside of said clip when moving axially towards said summit base, and wherein said portion of said blade maintained laterally at said level of said clipping hook is positioned along said first section of said blade. 3. The clip of claim 1, wherein said first portion of each said internal leg is provided with retention claws for the tang, said retention claws projecting inside said central space. 4. The clip of claim 1, wherein said first portion of each internal leg is provided with a clearance opening for said catch element carried by said internal leg.
